This is too easy to blow off as a hoax, but if you do some digging -- is it real?
There are ways to do digital forensics on files to determine if something has been digitally altered. I'm no expert in these techniques, but I feel I know enough to say these are indeed originals. Maybe not. Again, I'm not an expert and an expert photoshop artist familiar in these techniques could make it very difficult to discovery forgery. (fotoforensics.com)
I also understand that a lot of times news organizations and team sports will often prepare both so upon victory they're ready for sale immediately. However, a modicum of research doesn't shed any light on a "Trump" version being available. So if both were made only one has made it out to the public. ...and of course Newsweek is mum on the word.
Newsweek seems to have shown clear support for Hillary and so this isn't so shocking, if a bit extreme, but for them to leak this it would seem to have the opposite effect. Showing of the rig and making people more likely to vote against it, and for Trump. So was it Newsweek or an employee that leaked it? Not sure.
If there were a Newsweek employee who was also a Trump supporter, and whom may or may not know of their open bias toward Clinton, could have leaked it given the above and hoping that people will vote against rigging and for Trump.
In any regard, it's interesting that this comes out, now, and with very little time to dispute or create a cover story. Is it rigged? ...or is someone releasing partial info to make it seem like it is? ...or better still, is this a game of chess that's being played by a Trump supporter working for a company with a known bias as a means to generate more support for Trump and/or reputational risk for this specific company or media outlets in general?
Also, the wording is a bit partisan, but so is Newsweek. So is it believable?
Interesting though, ain't it?
